How do I properly encrypt/decrypt data between node.js with the crypto module (server side) and crypto-js (client side, react-native)?
NOTE: I'm using cryptojs in a react-native project, thus I can't use crypto on client. replacing crypto server side is not an option for me.
Server-side code:
var Crypto = require("crypto");
var Cipher = {
pass: "0123456789abcdef0123456789abcdef",
iv: "0123456789abcdef",
encript: function (msg) {
try {
var cipher = Crypto.createCipheriv("aes-256-cbc", this.pass, this.iv);
var hash = cipher.update(msg, 'utf8', "hex");
var hex = hash + cipher.final("hex");
return hex;
} catch (err) {
console.error(err);
return "";
}
},
decript: function (hex){
try {
var decipher = Crypto.createDecipheriv("aes-256-cbc", this.pass, this.iv);
var dec = decipher.update(hex, "hex", 'utf8');
return dec + decipher.final('utf8');
} catch (err) {
console.error(err);
return "";
}
}
}
Cipher.encript("i have an apple"); // 577267026f88f82ea286baf6bf089acb
Cipher.decript("577267026f88f82ea286baf6bf089acb"); // i have an apple
Client-side code
var CryptoJS = require("crypto-js");
var Cipher = {
pass: CryptoJS.enc.Hex.parse("0123456789abcdef0123456789abcdef"),
iv: CryptoJS.enc.Hex.parse("0123456789abcdef"),
encript: function (msg) {
try {
var options = { mode: CryptoJS.mode.CBC, iv: this.iv};
var json = CryptoJS.AES.encrypt(msg, this.pass, options);
return json.ciphertext.toString(CryptoJS.enc.Hex);
} catch (err) {
console.error(err);
return "";
}
},
decript: function (hex){
try {
// ???????????????????????????????????
// ???????????????????????????????????
} catch (err) {
console.error(err);
return "";
}
}
}
Cipher.encript("i have an apple"); // 405552d9a77ea9e29442057d27cd7aee
Cipher.decript(?????); // I have no Idea
